Direct Fuel Injection System
Purpose, Outline Engine output has been improved through the direct injection of fuel into the combustion chamber. High response can be because there is no time lag from when the fuel injection starts until the fuel is provided to the combustion chamber. Structure ...

Air Bag System Warning Alarm [Standard Deployment Control System]
Purpose The air bag system warning alarm notifies the driver that a malfunction occurred in the air bag system instead of the air bag system warning light. Function If a malfunction occurs in the air bag system while the air bag system warning light cannot illuminate, the a ...

Air Fuel Ratio (A/F) Sensor Heater Control
Outline Based on the control of the A/F sensor heater, a stabilized oxygen concentration is detected even at low exhaust temperatures, and feedback control of fuel injection even at cold engine start is made possible for improved cold temperature exhaust emission performance. ...
